PAPTEX 3CSSB603520 Triple Layer SSB Forming Fabric

3CSSB603520 Triple-Layer SSB Forming Fabric Selection

3CSSB603520 is a 2/5-shed triple-layer SSB forming fabric for paper-machine forming sections. Its technical sheet describes a 2-shed plain-weave paper side and a 5-shed satin-weave wear side. Review the intended machine position, current fabric and sheet requirements before confirming a replacement specification.

3CSSB603520 vs 3CSSB603020: what differs?

Both sheets record a 2/5-shed triple-layer construction, a warp density of 62.5–64.5 ends/cm, and Ø0.14 mm and Ø0.20 mm PET warp yarns. The following differences provide a starting point for comparing the two candidate models.

Both models also list Ø0.14 mm PET and PA weft yarns; the larger-yarn row is not the complete weft specification. Both sheets record water permeability of 52 s/5 L and specific elongation at 50 N of ≤0.45%. See the complete 3CSSB603020 forming fabric specifications for the alternative model.

How to use the comparison

These differences help frame a selection review; they do not establish which fabric will perform better on your machine. The sheets do not state the air-permeability test pressure or the calculation methods for FSI and DI. Confirm matching test and calculation methods before comparing these values with another supplier's data. An air-permeability difference is not a predicted increase in machine dewatering, and FSI or DI is not a guarantee of retention, sheet quality or service life.

The source sheets do not provide a model-specific paper-grade suitability table, operating-speed range or guaranteed lifetime. Those operating limits and application requirements need confirmation for the actual position.

What to send for a forming fabric selection review

• Paper grade, basis-weight range and the sheet issue you want to address.
• Former configuration, exact fabric position, operating speed, and fabric length and width.
• Current fabric model, construction, available specifications and paper-side, wear-side or damage photographs where available.
• Recent drainage, retention, marking, guiding or wear observations; include units and operating conditions with measurements.
• Available vacuum, tension and cleaning records, plus machine-builder requirements for the position.
